For the first time in history, regulators are requiring financial institutions to have a specific amount of liquid assets on hand to withstand a 30-day run by creditors and depositors, should a sudden crisis strike again. This is a right step to keep the system from freezing as happened in 2008.

However, will focusing on liquidity prevent what can devastate institutions in crises as experienced by Bear Stearns, Lehman and Wachovia? No, it will not, because institutional liquidity problems in crises are caused by a more fundamental factor.
